Flux Applications

Selective automated flux dispensing is utilized at certain stages in the assembly process where improved reliability and speed are required. Many applications include rework. Precision dot dispensing allows very tightly controlled volumes of flux to be accurately targeted to specific areas, thus preventing excess fluxing, which can result in cleaning issues or flowing and spreading to undesired areas. Camalot® dispensing machines excel in applying a wide array of flux formulations including No Clean (NC), Water Soluble (WS), Rosin Mildly Activated (RMA), and Rosin Activated (RA) for a full range of semiconductor and board assembly processes that include flip chip and advanced packaging. Paste or ‘tacky’ fluxes are also dispensed for BGA and µBGA sphere attachment, and for operations such as soldering flip chip components to various PCB substrates.

For decades, Camalot® has been the global leader in dispensing technology for electronic materials. From board-level assembly to advanced packaging to cutting-edge compound semiconductors, Camalot’s innovative solutions have kept our dispense systems solutions in the forefront.

Camalot® dispensing machines excel in the precise, highly accurate micro-dispensing of conductive adhesives and epoxy resins onto a variety of surfaces including silicon, silver, gold and copper.

Camalot® dispensing machines' ability to precisely dispense both materials at high speed using dual head technology delivers high throughput and efficiency in dam and fill applications. 

Camalot® precision dispense technology ensures successful application of adhesives for both corner/edge bonding processes. Edge/corner bonding is used as an alternative to underfill to add mechanical strength and reliability to BGAs and similar chip-scale packages (CSPs) and to increase reliability for drop testing.

Camalot’s advanced time/pressure dispensing technology precisely and consistently applies curable RTV gasketing fluids for a wide range of applications such as automotive electronics and aerospace where a robust form-in-place (FIP) gasket is required to provide environmental isolation for electronic components and assemblies.

Camalot® dispensers incorporate the most advanced deposition technology for solder paste dispensing, traditionally one of the most difficult materials to dispense consistently.

Surface Mount Adhesives (SMA’s) are typically used to hold SMT components in place on the bottom side of a PCB. These can range from small ‘chip’ components to large devices. The adhesive, usually in highly visible yellow or red colors, is dispensed typically in dot form and is heat-curable.

Thermal Interface Materials (TIMs) are often curable higher-viscosity fluids designed to conduct heat from one object to another. Typically, they are sandwiched between a heat-generating surface and the surface of a heat sink.

Underfill is used in a wide variety of packages and board-level assemblies, and Camalot® dispense machines, particularly the SmartStream® pump technology, perform fast, efficient, complete underfill for all types of packages reliably and repeatably.

UV-curable selective coatings can be precisely applied to critical areas of electronic components and assemblies using Camalot® dispense technology including SmartStream, a unique patented non-contact pump technology.
